Brazilian Portuguese version of the Patient Scar Assessment Questionnaire / Validação da versão em português do Patient Scar Assessment Questionnaire

Introduction: Scars and their associated signs and symptoms have the potential to impact many aspects of health. Given the growing number of individuals with new scars, it is essential to have reliable, sensitive, and specific assessment tools that analyze the influence that scars can have on the quality of life. The objective is translate the Patient Scar Assessment Questionnaire (PSAQ) into Portuguese, adapt it to the Brazilian cultural context, and test its reproducibility, reliability, and validity. Methods: The questionnaire was applied to 121 individuals with post-surgical scars consecutively selected at a plastic surgery clinic from January 2015 to June 2016. The PSAQ consists of 39 questions divided into five subscales: appearance, symptoms, perception, satisfaction with appearance, and symptoms. Then its reproducibility, face, content, and construct validity were analyzed. Internal consistency was tested using Cronbach's alpha coefficient, and construct validation was performed by correlating the translated instrument with the QualiFibro and Patient and Observer Scar Assessment Scale (POSAS) questionnaires. Results: Analysis of the internal consistency of the PSAQ subscales obtained values >0.70 in all domains, showing good internal consistency. Reproducibility was demonstrated using Pearson's correlation and the Bland-Altman method, and the outcomes showed good reproducibility. In construct validation, a significant correlation was observed in all PSAQ domains with POSAS and QualiFibro. Conclusion: The PSAQ was translated into Portuguese and adapted to Brazilian culture, reproducible and presenting face, content, and construct validity.

Is Balance Control Affected by Sleep Deprivation? A Systematic Review of the Impact of Sleep on the Control of Balance.

Background: Sleep is a complex physiological function that should be addressed from different perspectives and consider the circadian rhythm. Sleep deprivation, either acute or chronic, negatively affects several functions, including motor control. Balance control is essential in several daily life activities and balance problems are related to falls. Research Question: This review focuses on how sleep conditions impact balance control. Methods: Systematic literature review according to PRISMA guidelines. Results: The literature provided strong evidence that acute sleep deprivation impairs postural control. Chronic sleep deprivation as well as low sleep quality had similar effects, although there is a lower number of works addressing this issue. Furthermore, time awake worsens postural controls and it can be used to detect sleepiness and fatigue. The sleep deprivation showed a stronger negative effect on postural control when removing the visual information (eyes closed) than when reducing proprioceptive feedback (soft surface). There is scarce literature about the effects of chronotype, circadian patterns and chronic sleep deprivation, a frequent problem, on balance control; however they consistently indicate that there is an relationship between them. Most of the studies only consider one-night (acute) sleep deprivation without monitoring prior sleep conditions and the circadian rhythm phase of the participants. However, a few studies indicated that these factors must be considered. Significance: These results suggest that the sleep conditions of a subject should be considered for several days prior to balance control tests. Therefore, we propose a revision of current postural measurement protocols to include sleep assessment, such as sleep quality questionnaires or actimetry, and to consider the circadian rhythm of the participants to plan the hour of the tests.

Two- and Three-Segment Surgically Assisted Rapid Maxillary Expansion: A Clinical Trial.

BACKGROUND: The literature shows no consensus on whether two- or three-segment surgically assisted rapid maxillary expansion is the best operative technique. METHODS: The present clinical trial was designed to compare the outcome of two- and three-segment osteotomy surgically assisted rapid maxillary expansion. Thirty-two adult patients with transverse maxillary deficiency greater than or equal to 5 mm were randomly assigned to two- and three-segment groups (n = 16). Dimensional and psychological assessments (Oral Health Impact Profile and Brazilian Orthognathic Quality of Life Questionnaire) were carried out before surgical intervention and at one of the following time points: completion of expansion, removal of expanding device, 6 months after completion of expansion, or 10 months after completion of expansion. Dimensional assessments for asymmetric expansion of the maxilla and for changes in the area and volume of the palatine vault were performed on digital data from tomographic and laser scanning with the aid of an engineering inspection software. RESULTS: No statistically significant differences were found in asymmetry or stability outcomes between groups. The psychological benefit provided by the three-segment technique did not spread through the domains of the quality-of-life questionnaires. CONCLUSIONS: The current findings suggest that three-segment surgically assisted rapid maxillary expansion outcomes do not exceed those obtained with its two-segment counterpart regarding symmetry of maxillary expansion and stability of area and volume of the palatine vault. Furthermore, psychological nuances evidenced in two- and three-segment groups with the tools used play a limited, short-lasting role, or a specific, more sensitive assessment tool needs to be developed. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

JPEG and raw image files compared to direct measurement of the breast region.

PURPOSE: To compare JPEG and RAW image file extensions to direct measurement of the breast region. METHODS: Points were marked on the breasts and arms of 40 female volunteers. The joining of these points in each hemibody formed seven linear segments, one angular segment and one median segment common to both hemibodies. Volunteers were photographed in a standardized fashion and evaluated by three raters using the software Adobe Photoshop CS6® and three image file extensions (RAW, high resolution JPEG and low resolution JPEG); values were compared to direct anthropometry. RESULTS: All variables had interclass correlation coefficient higher than 0.8 (ICC>0.8). On average, all variables in all methods showed differences (p<0.05) when compared to direct measurement. A formula was created for each segment and each image file extension in comparison with the direct measurement. CONCLUSION: Measurements were similar among the correlated JPEG and RAW image file extensions but differed from the actual breast measurement obtained with a caliper.

Medidas da região mamária: antropometria direta ou indireta? / Breast region measurements: direct or indirect anthropometry?

Introdução: As medidas precisas dos seios femininos são difíceis de obter devido à topografia, volume e projeções presentes. Portanto, este estudo teve como objetivo comparar medidas da região mamária obtidas por antropometria direta (fita métrica) e indireta (fotogrametria computadorizada). Métodos: Este é um estudo transversal. Foram avaliadas 40 mulheres, com idades entre 18 e 60 anos, índice de massa corporal <29,2 kg / m², que tinham 12 marcas anatômicas na região das mamas e braços. A união desses pontos formou 7 segmentos lineares e 1 ângulo para cada hemicorpo, e 1 segmento comum a ambos os hemicorpos. As fotografias obtidas de forma padronizada foram mensuradas por fotogrametria computadorizada com o software Image Tool®. Os mesmos segmentos também foram medidos por antropometria direta, com fita métrica. O teste de Shapiro-Wilk foi usado para avaliar se cada variável tinha uma distribuição normal. O teste de correlação de Pearson foi aplicado para avaliar a correlação entre os diferentes métodos: antropometria direta (medição com fita) e indireta (fotogrametria por Image Tool®). O nível de significância adotado para os testes estatísticos foi de 5% (p <0,05). Resultados: Diferenças significativas foram encontradas nas comparações entre a fita métrica e a fotogrametria computadorizada para todos os segmentos analisados (p> 0,05). Conclusão: Existe correlação entre as medidas dos seios da face obtidas pela antropometria direta (medição com fita métrica) e indireta (fotogrametria pelo software Image Tool®), principalmente nas medidas da papila.

Introduction: Accurate female breast measurements are difficult due to the topography, volume, and projections present there. Therefore, this study aimed to compare breast region measurements obtained by direct (tape measurement) and indirect (computer-based photogrammetry) anthropometry. Methods: This is a transversal study. Forty women were evaluated, aged 18-60 years, body mass index of <29.2kg/m² that had 12 anatomical marks on the breast region and arms. These points' union formed 7 linear segments and 1 angle for each hemibody, and 1 segment common to both hemibodies. The photographs obtained in a standardized way were measured using computer-based photogrammetry with Image ToolTM software. The same segments were also measured by direct anthropometry, using a tape measure. The Shapiro-Wilk test was used to assess whether each variable was normally distributed. The Pearson correlation test was applied to evaluate the correlation between different methods: the direct (tape measurement) and indirect (photogrammetry by Image ToolTM) anthropometry. The significance level adopted for statistical tests was 5% (p<0,05). Results: Significant differences were found in the comparisons between the tape measurement and computer-based photogrammetry for all segments analyzed (p>0.05). Conclusion: There is a correlation between the breast measurements obtained by direct (tape measurement) and indirect (photogrammetry by Image ToolTM software) anthropometry, especially the papilla measures.

Comparison of sleep quality assessed by actigraphy and questionnaires to healthy subjects.

Sleep quality analysis is crucial for human health and it is related to duration, rhythm and quality. The goal of this study is to analyze objective assessment of the sleep-wake cycles with actigraphy, subjective questionnaires and their relationship with sleep quality indices. A wearable actigraph registered the sleep habits of 41 healthy subjects for 9 days. Afterwards, the subjects filled two questionnaires about sleep quality (Pittsburgh Sleep Quality Index) and sleepiness (Epworth Sleepiness Scale). The subjects were divided into two groups based on cut-off scores and the actigraphy parameters were compared between groups. Group 1 in ESS and PSQI categorization had less diurnal sleepiness and better sleep quality, respectively, than Group 2. Measurements of regularity (IS), fragmentation (IV), active phase amplitude (M10), rest amplitude (L5), and relative amplitude (RA) were compared between groups. Group 2 had higher L5 values. Parameter L5 (lowest of 5 consecutive hours of activity) was concluded to be relevant to identify the sleep conditions of the subjects.

Social jetlag impairs balance control.

We assessed the impact of a common sleep disturbance, the social jetlag, on postural control during a period involving workdays and free days. The sleep habits of 30 healthy subjects were registered with a wrist actimeter for nine days (starting on Friday) and they participated in a set of four postural control tests carried out on Friday and on Monday. In addition, the subjects filled questionnaires about their sleep conditions and preferences. Actimetry measurements were used to calculate the Mid Sleep Phase (MSP). The difference between the MSP values on the workdays and free days measures the social jetlag. There were significant differences in sleep variables between workdays and free days. Postural control performance improved on Monday, after free sleep over the weekend, when compared with the tests performed on Friday. It seems that social jetlag affects brain areas involved in the control of posture, such as thalamus and the prefrontal cortex as well as the cerebellum, resulting in a worse performance in postural control. The performance improvement in the posture tests after the free days could be attributed to a lower sleep debt.

Heart rate variability based on risk stratification for type 2 diabetes mellitus.

OBJECTIVE: To evaluate heart rate variability among adults with different risk levels for type 2 diabetes mellitus. METHODS: The risk for type 2 diabetes mellitus was assessed in 130 participants (89 females) based on the questionnaire Finnish Diabetes Risk Score and was classified as low risk (n=26), slightly elevated risk (n=41), moderate risk (n=27) and high risk (n=32). To measure heart rate variability, a heart-rate monitor Polar S810i® was employed to obtain RR series for each individual, at rest, for 5 minutes, followed by analysis of linear and nonlinear indexes. RESULTS: The groups at higher risk of type 2 diabetes mellitus had significantly lower linear and nonlinear heart rate variability indexes. CONCLUSION: The individuals at high risk for type 2 diabetes mellitus have lower heart rate variability.

Low-dose resveratrol supplementation on heart rate variability in hypertensive volunteers: a controlled double-blind trial / Suplementação de baixa dose de resveratrol na variabilidade da frequência cardíaca em hipertensos: ensaio clinico controlado e duplo cego

OBJECTIVE: Hypertension decreases the heart rate variability (HRV). Resveratrol, a phenolic compound found in grapes and their products, has been explored for its potential to treat hypertension. We evaluated the effects of low-dose resveratrol on HRV in hypertensive volunteers. METHOD: Twenty-one hypertensive volunteers of both sexes were supplemented with resveratrol (n = 11) or placebo (n = 10) for 30 days. HRV parameters were measured before and during a standardized treadmill exercise. One resveratrol- and 3 placebo-treated patients were lost to follow-up. RESULTS: There were no anthropometric differences between resveratrol (n = 10) and placebo (n = 7) other than a difference in body mass index. The measured HRV parameters did not differ between resveratrol and placebo, or between control and treadmill exercise. CONCLUSION: Low-dose resveratrol did not alter HRV in hypertensive patients.

OBJETIVO: A hipertensão arterial diminui a variabilidade da frequência cardíaca (VFC). Resveratrol têm sido estudado como tendo potencial para o tratamento da hipertensão. Foram avaliados os efeitos de baixas doses de resveratrol na variabilidade da frequência cardíaca em voluntários hipertensos. MÉTODO: Vinte e um voluntários hipertensos, de ambos os sexos foram suplementados com resveratrol (n = 11) ou placebo (n = 10) durante 30 dias. Parâmetros da VFC foram medidos antes e durante o exercício em esteira padronizado. Um paciente tratado com resveratrol e três tratados com placebo foram perdidos. RESULTADOS: Não houve diferenças antropométricas entre os integrantes dos grupos resveratrol (n = 10) vs. placebo (n = 7), exceto uma diferença de índice de massa corporal. Não foram observadas diferenças para nenhum dos parâmetros da VFC entre resveratrol vs. placebo, ou entre controle vs. exercício em esteira. CONCLUSÃO: A baixa dose de resveratrol não afetou a VFC em hipertensos.

Ground reaction force patterns during gait in patients with lower limb lymphedema / Forças de reação ao solo durante a marcha de pacientes com linfedema de membro inferior

Although gait problems have been reported in patients with lower limb lymphedema (LLL), the gait pattern (GP) changes have not been documented yet. However, it is possible that patients with LLL show abnormal GP that can be related to biomechanical complications related to osteoarthritis or falls affecting the quality of life. Ground reaction force analysis during gait allows objective assessment of the patients and it can be used to plan a rehabilitation approach. Objective: To analyze the GRF during gait in patients LLL. Methods: An experimental descriptive study was realized with twenty-three LLL patients, both unilateral and bilateral and classified as moderate and severe, participated in the experiments. The patients walked on a force plate while the three ground reaction force (GRF) components, vertical, mediolateral (M-L) and anteroposterior (A-P), under their feet were recorded and analyzed. Results: In the patients with unilateral lymphedema, either moderate or severe, the vertical GRF components of the affected limb were similar to the sound one and also resembling those found in healthy adults. The M-L GRF was smaller in the non-affected side. In patients with bilateral lymphedema gait speed was significantly slower. More interestingly, the vertical GRF pattern was flat, not showing the typical 2-peak shape. Finally, the large M-L forces found suggest gait stability problems. Conclusions: The patients showed abnormal GRF patterns, including compensation with the non-affected leg. The GRF variability was higher in the patients with severe unilateral lymphedema. Bilateral lymphedema results in lower A-P forces. Stance phase duration was longer in patients with bilateral and severe lymphedema

Chronic Low Quality Sleep Impairs Postural Control in Healthy Adults.

The lack of sleep, both in quality and quantity, is an increasing problem in modern society, often related to workload and stress. A number of studies have addressed the effects of acute (total) sleep deprivation on postural control. However, up to date, the effects of chronic sleep deficits, either in quantity or quality, have not been analyzed. Thirty healthy adults participated in the study that consisted of registering activity with a wrist actigraph for more than a week before performing a series of postural control tests. Sleep and circadian rhythm variables were correlated and the sum of activity of the least active 5-h period, L5, a rhythm variable, obtained the greater coefficient value with sleep quality variables (wake after sleep onset WASO and efficiency sleep). Cluster analysis was performed to classify subjects into two groups based on L5 (low and high). The balance tests scores used to asses postural control were measured using Biodex Balance System and were compared between the two groups with different sleep quality. The postural tests were divided into dynamic (platform tilt with eyes open, closed and cursor) and static (clinical test of sensory integration). The results showed that during the tests with eyes closed, the group with worse sleep quality had also worse postural control performance. Lack of vision impairs postural balance more deeply in subjects with chronic sleep inefficiency. Chronic poor sleep quality impairs postural control similarly to total sleep deprivation.

Effect of High- and Low-Frequency Transcutaneous Electrical Nerve Stimulation on Angiogenesis and Myofibroblast Proliferation in Acute Excisional Wounds in Rat Skin.

OBJECTIVE: This study evaluated the effects of high- (HF) and low-frequency (LF) transcutaneous electrical nerve stimulation on angiogenesis and myofibroblast proliferation in acute excisional wounds in rat skin. DESIGN: This was an experimental controlled and randomized study. PARTICIPANTS: An excisional wound was made on the back of 90 adult male EPM1-Wistar rats using an 8-mm punch. INTERVENTIONS: The animals were randomly assigned to the HF group (80 Hz), LF group (5 Hz), or control group. Transcutaneous electrical nerve stimulation (pulse duration, 200 microseconds; current amplitude, 15 mA) was delivered (session length, 60 minutes) on 3 consecutive days. MEAN OUTCOME MEASURE: Immunohistochemistry was performed on postoperative days 3, 7, and 14 for counting blood vessels and myofibroblasts. MEAN OUTCOME RESULTS: The LF group had significantly more blood vessels than the HF group on day 3 (P = .004). The HF group had significantly less blood vessels than did the control group on days 7 (P = .002) and 14 (P = .034) and less myofibroblasts than did both the LF and control groups on day 3 (P = .004) and less than did the control group on day 7 (P = .001). CONCLUSION: There seems to be a benefit to the use of LF transcutaneous electrical nerve stimulation in the healing of acute excisional wounds, but further studies are warranted.

Quais Fatores Influenciam a Taxa de Aprovação na Disciplina de Anatomia Humana? / What Factors Influence the Approval Ratings in the Discipline of Human Anatomy?

RESUMO A Anatomia Humana (AH) é uma disciplina básica para todos os estudantes dos cursos superiores das áreas da saúde e biológica. A maior parte a considera de conteúdo difícil. O ensino da AH precisa ser repensado no contexto da política atual de acesso amplo ao ensino superior. E corresponder ao dever das instituições de proporcionar ao estudante uma formação de qualidade com vistas à formação de um profissional crítico e de perfil criativo frente às distintas situações do cotidiano. É preciso entender possíveis fatores que levam às elevadas taxas de reprovação nesta disciplina. Portanto, o objetivo do presente estudo foi relacionar o resultado do vestibular/Enem com hábitos de estudo e desejo profissional no desempenho acadêmico da disciplina dos alunos dos cursos de Educação Física, Ciências Biológicas e Nutrição do IF Sudeste MG. Foram entrevistados 129 alunos. A pontuação do vestibular/Enem foi maior entre os aprovados em AH; não houve entre os grupos diferença quantitativa nas horas de estudo e tampouco na escolha do curso, que ocorreu por opção do aluno (versus por falta de opção).

ABSTRACT Human Anatomy (HA) is a basic discipline in health and biological sciences indispensable to all academic students. Most of them consider its content very difficult. The teaching of HA needs to be rethought in the context of the current policy, which provides increasing access to higher education. It needs to be compatible with the institutions’ ability to meet their obligations and therefore, provide the student with a qualityeducation aimed at the formation of critical thinking and a creative profile to deal with different situations of everyday life. One must understand the potential factors that lead to high failure rates in this discipline. Therefore, the present study aimed to correlate the results of the entrance examination/ENEM with study habits and professional goals of the students’ academic performance in Physical Education, Biological Sciences and Nutrition courses of the IF Sudeste MG University. A total of 129 students were interviewed. The entrance examination or ENEM score was higher among those who passed in HA; there was no quantitative difference between the groups either in study hours or in the choice of course made by the student.

Photographs for anthropometric measurements of the breast region. Are there limitations?

PURPOSE: To determine the limitations of the photographs used to obtain the anthropometric measurements of the breast region. METHODS: Five women, between the ages of 18 to 60 years, were evaluated. Photographs of the frontal and left and right profile views of their breasts were taken. Based on the current literature, the most commonly used anthropometric and anatomic landmarks for breast measurement were marked in their different positions. The different points were used to evaluate if the direct anthropometry was possible in a standardized way and determine how the points and the positions can to be used in any breast measurements. RESULTS: There were some limitations to the use of defining points of the breast fold, as well as of its lower portion and lateral extension positions in both profiles. CONCLUSION: The defining points of the breast fold and the profile photographs have some limitations and we suggested how the points and positions can be used for breasts measurements.

New approach to the understanding of keloid: psychoneuroimmune-endocrine aspects.

The skin is a dynamic and complex organ that relies on the interrelation among different cell types, macromolecules, and signaling pathways. Further, the skin has interactions with its own appendages and other organs such as the sebaceous glands and hair follicles, the kidney, and adrenal glands; systems such as the central nervous system; and axes such as the hypothalamic-pituitary-adrenal axis. These continuous connections give the skin its versatility, and when an injury is caused, some triggers start a cascade of events designed to restore its integrity. Nowadays, it is known that this psychoneuroimmune-endocrine intercommunication modulates both the homeostatic condition and the healing process. In this sense, the skin conditions before a trauma, whether of endogenous (acne) or exogenous origin (injury or surgical incision), could regulate the process of tissue repair. Most skin diseases such as psoriasis and atopic dermatitis, among others, have in their pathophysiology a psychogenic component that triggers integrated actions in the nervous, immune, and endocrine systems. However, fibroproliferative disorders of wound healing, such as hypertrophic scar and keloid, are not yet included in this listing, despite showing correlation with stress, especially with the psychosocial character. This review, by understanding the "brain-skin connection", presents evidence that allows us to understand the keloid as a psychomediated disease.

Image analysis software versus direct anthropometry for breast measurements.

PURPOSE: To compare breast measurements performed using the software packages ImageTool(r), AutoCAD(r) and Adobe Photoshop(r) with direct anthropometric measurements. METHODS: Points were marked on the breasts and arms of 40 volunteer women aged between 18 and 60 years. When connecting the points, seven linear segments and one angular measurement on each half of the body, and one medial segment common to both body halves were defined. The volunteers were photographed in a standardized manner. Photogrammetric measurements were performed by three independent observers using the three software packages and compared to direct anthropometric measurements made with calipers and a protractor. RESULTS: Measurements obtained with AutoCAD(r) were the most reproducible and those made with ImageTool(r) were the most similar to direct anthropometry, while measurements with Adobe Photoshop(r) showed the largest differences. Except for angular measurements, significant differences were found between measurements of line segments made using the three software packages and those obtained by direct anthropometry. CONCLUSION: AutoCAD(r) provided the highest precision and intermediate accuracy; ImageTool(r) had the highest accuracy and lowest precision; and Adobe Photoshop(r) showed intermediate precision and the worst accuracy among the three software packages.
